It's certainly possible, however you'll then need to provide the few
critical features that bluetoothd provides through some other means.
E.g. the BlueZ for Android implementation (see android/ subdirectory)
uses neither D-Bus nor bluetoothd. You'd still need some daemon to
provide an SDP server ("sdptool add.." talks to bluetoothd which manages
the local service records) and to handle pairing related functionality
such as responding to PIN code/passkey requests and storing the
resulting link keys (and reloading them once your daemon restarts).
